vadonka with your kernel (both 2.6.32.y and last 2 release of 3.y) i can't install some games like fruit ninja thd, soulcraft thd and bumbee because the play store say that my device is not compatible...you changed something?
[LG Optimus 2x] wkpark:
No you wrong it is critical bug not shown in the original kernel 3.0.8 tree
[LG Optimus 2x] Keltek:
Installed 1204171427-ETaNa_OC_DS_OTF and I have to increase lowest frequency to 324. Without it the device is "soft" restarting (performing boot without asking SIM PIN).
[LG Optimus 2x] hadi_rena:
Did you change LCD density? AFAIK that the root cause of market incompatibility...

Just restore LCD density to 240, reboot, wipe market data, re-run market, wait a few minute to resync completely...

[LG Optimus 2x] joe1660:
I think I found the problem solution for system. is anybody of you that you have the system r/w problem, stop some of the system services? i have stop some services with autorun manager and i had the problem. when i start the system services again the problem disapear after a restart. but i am not sure if this was the problem, so i need the people that have this problem to confirm that
[LG Optimus 2x] joe1660:
Forget it after second reboot I can't mount the system again as rw

@vadonka: I found bug in kernel 3.0.y branch. This kernel lost ability move app to SD. I try to move some app (I try with Where is my Water game) to SD card and system responded with failed to moved. But if I flash kernel 2.0.y then there is no problem.

Step to reproduce:

1. Settings > Application > Manage Application

2. Locate Where is my Water (I install this game from kernel 2.0.y)

3. Hit move to SD

4. System responded with failed

Kernel Used: 1204160224-ETaNa_OC_OTF-3.0.y.zip

Does anyone have similar problem with me :confused:

-- UPDATED --

Problem fixed in latest kernel... Just updated to 17 april version and move to SD working properly...

Case Closed :D
[LG Optimus 2x] rafaelsartori:

"OS Monitor"

Yesterday I noticed another strange error, different from previous I posted.. about tegra.. an error on UART:
[LG Optimus 2x] vadonka:
im uploaded a new version. just a few bugfix and the top priority is optimize the battery life to get better.

hopefuly this version give as a better battery life, at least i experienced a promising results.

try it :)
[LG Optimus 2x] vadonka:
try to activate the trace debug and you will see this in the 3.0.8 too (i check this)

and its not a critical bug :)

its a known bug what is already fixed in the x86 version, but it seems not in the arm, its related to the might_sleep() call
[LG Optimus 2x] vadonka:
this is because the trace debug. all of this happened in previously too just you dont see it. its not a real error anyway.

im disabled the verbose debug in the today version, so you dont see this anymore.

it seems the verbose debug log confuse some people :)

currently non of this errors are critical or cause noticable issues, only the high battery drain what remain in the high priority bug list.

but im working on that :)
[LG Optimus 2x] yarisd4dturbo:
Vadonka, little ot request :), can you build a simple cyano original kernel with voodoo sound and oc capability? I know you are busy with your kernel, but for my needs i prefer a kernel without any tweak or patch inside :D...thx in advance :)

[LG Optimus 2x] fitipardi:
yes, the last kernel (3.0.28-ETaNa_OC_OTF) work better than previous, better battery live and a little bit better quadrant, with kang 89.

great vadonka
[LG Optimus 2x] extreme79:
Today I'll try the new release!

Vadonka for president! :D :D

ok.. I've installed the kernel.. WiFi deactivated and mobile data activated.. monitoring in progress :D
[LG Optimus 2x] silentmelodies:
Lol

The new version is indeed very good :D

One thing that could be improved though is the booting time. I reckon it was faster in the 2.6.y version.
[LG Optimus 2x] vadonka:
updated, try this latest version it should be fix the boot problem on some devices.

here is my latest result of the battery test:

i dont charge the battery for reason, but you see that drain very slowly in standby mode, i loss only a few percent in 10-15 hours.
[LG Optimus 2x] new2city:
thanks, you really put your time on it..
[LG Optimus 2x] vadonka:
who had boot problem with the previos version please try this and give me a feedback.
[LG Optimus 2x] Trystan34:
Hi I want to try the power save version. I am currently running Temasek's CM7 204-33 KANG and going to be updating to 34 with this kernel. What are the steps to installing this with the kang? I have ironkrnl (0mb hack)

Do I need to wipe any thing?
[LG Optimus 2x] vadonka:
no, the kernel installer will wipe the dalvik cache and the cache automatically.

install temasek kang, then this kernel and done :)
[LG Optimus 2x] kayzee:
Minor voltage adjustment!!!

Thanks so much!!
[LG Optimus 2x] Trystan34:
Thank you, do I need to make a nandroid backup incase?
[LG Optimus 2x] vadonka:
always need!
[LG Optimus 2x] vadonka:
im increasing the 770mV to back 800mV, make sure that avoid the bsod in low level

you can still undervolt if you want, but it not make any difference in the battery life
[LG Optimus 2x] fuxmen:
on what frequency in powersave there are no second core activation?
[LG Optimus 2x] Shadowchaz:
I've noticed one thing using miui all my battery stats show 0% and when I charged last night the battery showed I was out of charge until I rebooted then it corrected itself.

Cheers for your hard work though other than that its rock solid for me and I use my phone intesnsively yesterday
[LG Optimus 2x] vadonka:
normal mode

second core activated if the cpu freq is above 655Mhz for at least 200msec

second core deactivated if the cpu freq is below 503Mhz for at least 1500msec

powersave mode

second core activated if the cpu freq is above 655Mhz for at least 300msec

second core deactivated if the cpu freq is below 655Mhz for at least 1000msec

Also a good alternative that activate the second core at 816mhz, since the powersave version have a different freq step.

the powersave mode activate the second core a little later and deactivate sooner.

but not much to avoid the lag.
[LG Optimus 2x] Trystan34:
Under Power save kernel which one must I use?

base version?

shared memory version?

traditional ramhack if you have problem with the shared version
[LG Optimus 2x] ron_gangte:
I use Shared Memory Version. And I have a stable phone with almost no lags at all.

But then you can choose what you want.

PS : Helpful Posts are the ones you are supposed to thank. So "Thank Me"..!! :-P :-)
[LG Optimus 2x] Trystan34:
Is the bsod or other freezes on the shared memory version or base version?
[LG Optimus 2x] ron_gangte:
Haven't tried the other versions. But the Shared Memory Version that I use hasn't given me any BSOD or Freezes. :-)
[LG Optimus 2x] Trystan34:
Thank you.
[LG Optimus 2x] vadonka:
try the normal base version first. it should be safe.
[LG Optimus 2x] Trystan34:
Oops have just flashed the shared memory version.
[LG Optimus 2x] ron_gangte:
No worries. You can just flash the normal version over it. And you do not have to flash anything else if the Shared Memory Version does not cause any sort of problem for you.
[LG Optimus 2x] eyronic:
You don't boot every time so don't mind it much. :P
[LG Optimus 2x] extreme79:
After 1hr of testing.. now way :(

Battery drain is my friend.

Comparing the decay speed during the morning (17Apr kernel) with actual decay speed (18Apr kernel) I see the same battery drain speed, no changes. :(

Actually my phone network coverage is only Edge.

One positive thing :D : the phone is now cool and not overheated (later I'll test if the same is true under 3g too)

Later I'll post the comparative graph, with morning, actual and under wi-fi decay speed.
[LG Optimus 2x] pitrus-:
Less battery power turned into hear, more power to there phone. Unless there phone somehow manage to not get hot while cpu is working.... You should at least get an hour or two extra. =)

[LG Optimus 2x] vadonka:
i found an incompatibility with the kernel 3.0.y and the setcpu (i dont know the other cpu apps)

the problem is if the setcpu change the cpu speed, the cpu1 core is always active, never will be deactive.

try to use your favorit cpu manager app only for the undervolt if you dont like the etana app undervolt part, but dont use profiles or min, max definitions.

use the cm7 built in cpu settings in the performance menu.

in that case the second core will be deactivate every time if reach the threshold levels.

this is not happened with the kernel 2.6.32.y, so its some kind of incompatibility with the new kernel.

if you using the stock non overclocked version but using a cpu manager app you have this problem too if you using profiles.

the kernel capable to maximize the screen off cpu freq, use that option, the other profiles not needed really.

of course if the second core always active its cause battery drain.
[LG Optimus 2x] extreme79:
Mmmmm I use PimpMyCpu v5.. and use max-min frq with various profiles..

Ok! Later I'll try the trick! :D

If that works.. You will be my hero! :p :D

(but I don't undrestand why battery draining happen with mobile data, but not with wifi.. how cpu frequency is related with mobile/wifi?)
[LG Optimus 2x] Nova163:
Do you think it's the cause of a battery drain I'm experiencing with the latest kernel?

I've attached a graph of my battery, you see that the battery usage is way lower when I reverted to the previous version

Edit: upload failed, I'll try to upload it later. Anyway, there's a battery drain for no apparent reason
[LG Optimus 2x] vadonka:
nothing, but if the both core active its cause battery drain too.

by the way im removed the ro.ril part from the build.prop tweaks, it seems better that not playing with that values. owain can confirm that too :)
[LG Optimus 2x] vadonka:
try the latest version, im deactivated many unneded features in the kernel.
[LG Optimus 2x] joe1660:
When I try to install your kernel it stops and says "error: packing kernel failed"
[LG Optimus 2x] vadonka:
it means that the boot.img was not created succesfuly after calling the mkbootimg. open an adb shell after you give this error and call the 'mount' command and paste the output to here. its possible that your tmp partition is not writeable

and pull the recovery.log from the /tmp and attach too.
[LG Optimus 2x] joe1660:

[LG Optimus 2x] joe1660:
Now I am with the new kernel and the system is the same. I can't make it r/w.
[LG Optimus 2x] fuxmen:
Is that thing with setcpu if i good undesrand, if I use it my phone never goes to deep sleep ?

I uninstaled setcpu will se now
[LG Optimus 2x] rexren:
When install a new kernel, I will check if CPU1 core can be deactive normally.

New setcpu version will have Cpu1 core could not be deactive problem.

Setcpu 2.2.4 work fine with kernel 3.0.y and setcpu 3.0.2 doesn't.

Setcpu 3.0.2 work fine with cm7 stock kernel.
[LG Optimus 2x] vadonka:
i can say that the battery life way better now. so the setcpu/cpu1 issue cause battery drain for sure. im not say that something else not drain the battery but this is the one part of the problem. its right the older setcpu working fine, so maybe other cpu manager app working fine too.

you can check the cpu1 status with the 'system panel' app (market)
[LG Optimus 2x] joe1660:
So strange before five minutes I was able to install ril with getril and now I can't again. the system mount problem is not always . It's only sometimes. So strange
[LG Optimus 2x] extreme79:
No way for me.. :(

Removed pimpmycpu v5

Reinstalled Kernel + cache & dalvik cleaning

Reboot

Removed pimpmycpu included with the kernel (after deleting app data)

Fixed a max & min cpu freq from cyano settings

Enabled TwekIO parameters (sqllite defrag, undervolt, powersave parameter to 2)

Rebooted into recovery, deleted cache, deleted dalvik.

Rebooted & connected to charger.

(ROM reinstalled from zero some days ago)

Disconnected @94% 3hrs and 20min ago

Deactivated wiFi and activated mobile data 3g+2g (but only edge coverage in my room).

Now @49% without any type activity on the phone! Nothing.. only turning the screen 6 times for a little bounch of seconds.

So.. 13,5% in 1hr.. too too much for a phone over a desk, without any apparent reason.. no app running, nothing.

Watching the dmsg log I've many notice about the correct CPU1 shutdown.

I can't understand why with this new kernel the battery is drained at this speed :confused: :confused:

BB725+RIL218 incompatible with 3.0.x?

Let me know friends.. I'm the only one with this high drain?
[LG Optimus 2x] joe1660:
look at that its amazing score in quadrant

follow it exactly and it won't wipe your data.

First I tought that only the first step will be enough but it wasn't.

So follow all the step and then you can have r/w in system.

In my case it was just to get "getril" to work.

After flashing the latest version of etana stock ds kernel. The battery frustrated. For example, from 65% to 70% and sudden drop to 45% and later go back to 68%. Is there somethings goes wrong?
[LG Optimus 2x] qgtxqj:
That's the way DS drivers working called funky by vadonka
[LG Optimus 2x] mat369:
Three random reboot yesterday with the previous version, a bsod this morning with the Apr18 version (with "stay awake" activate and CPU @ min 312)

I think I don't have the battery drain problem, but I'm sure that I've got some stability problems.

I had not had any bsod since a long time...

Anyway, this kernel still the best! Thanks for all :)
[LG Optimus 2x] csunny95:
Sorry, may I know what is the meaning of funky and what's special about DS drivers?

Also, can the frustration problem be sloved?
[LG Optimus 2x] fuxmen:
DS drivers gives better battery life, but cost of that are this funny readings :)

If U want to have better battery U just need to used to it :) Or use version without DS batt driver
[LG Optimus 2x] Nova163:
When your phone is draining the battery heavily the reading will drop quickly, and when you stop using your phone it will go back to the real level of charge.
[LG Optimus 2x] alakyr:
thank you very much!!!

btw this morning at 4.30am was at 100% battery....i unplugged it and at 6.30am when i woke up it was at 98% with wifi!!! i didn't believed it then i went in cwm and wiped cache, dalvik and battery stat because I thought it was an error but at boot the % was still at 98%...

gj with battery vadonka!
[LG Optimus 2x] vadonka:
thx!

i try to advance the cpu speed management

- battery and charger overheat protection already working with the spica basis, and advanced a little

- screen off max freq is also working, so no need a setcpu profile for this

- limit max cpu speed when the battery level dropped below to a specific level, im still working on this, but its looks good.

if all of this will working together no need to apply cpu profiles, dont even need to use any third party app

everything will be handled with the kernel :)
[LG Optimus 2x] eyronic:
I only need 3 profiles.

Screen on, screen off, and in call. Is in call profile possible to be integrated in the kernel?
[LG Optimus 2x] vadonka:
well the in call profile is a bit harder i think :)

but when you are in call probably your screen if off too, so the screen off profile is also working in that case
[LG Optimus 2x] alakyr:
you are saying that you are integrating the profile in the kernel then no need to set it manually? you are the best!!!

btw if you need some tester for this stuffs i'll be happy to help you! just need to know how to check that everythings is working =P

EDIT: I use all your profile in the main post except the one "charging" with oc because i find it useless and i added a proile "screen on" @ 1015mhz (stock then) because at woke up the frequency was the one of the profile "screen off"

EDIT2: imo 500mhz for the calling profile is a bit low...i suggest to raise it up to 655mhz because sometimes during call there is a lot of lags and slow down

[LG Optimus 2x] hadi_rena:
Vadonka can you help us found the culprit for battery drain from better battery stat output? I admit it I doesn't really understand. What I know is partial wakelock can cause battery drain but I confused how to remove the partial wakelock.

If you can help us I really thankful for this. I only have around 20 hour of battery with your kernel. If I use LG kernel than only 8 hour :(
[LG Optimus 2x] vadonka:
the better battery stats have an option that 'dump to file'

so pick the partial wakelocks and kernel wakelocks option and dump to file both of them.

Then the cm7 installer script is probably not able to backup your system apps because your /system filesystem is corrupted. You will probably have to format it. How to do this and how to avoid the fs corruption, has been posted several times a few pages back.

Sure!

To avoid any errors I've just patched for r/w issue, I've reinstalled my rom, cleaned cache& dalvik, reinstalled mount patch for my rom (to have stock style mount).

Ther only "strange" thing on wakelocks is the SipWakeLock.

Yes, I've a voip account added to the system (Settings>Calls settings>Internet call settings) but NOT enabled to receive calls.. so it could not be used by the system and then it must not generate wakelocks.

There are something else in the "others" that I cannot explain.. like a lot of time with no signal, and next with no or unknown signal (:confused:).

You have the oc version or the stock? Cause the oc version have several step to underclock frequency like vadonka told 1/2 pages ago instead the stock have only 2 steps (216 and 1015)

[LG Optimus 2x] extreme79:
Good Morning!

Seems that battery draining is gone after Voip account removal magic step.

Actually on battery since 2hr and -8% of battery.

Seems to be SO good. (OC kernel but not overclocked)

For the people experimenting the battery draining.. try to check if you have Voip account in Settings.

Next try to install BetterBatteryStats, it can help a lot!

So.. A question for Vadonka: is a kernel or Rom related related issue? Because is so strange that the Voip account cause that type of drain when unused and not set to receive calls.

Hi,

To get things woking on my phone again I have run backtoext3, then installed KANG, then installed latest kernal, and it's all working, no read write problems, so happy about that! I've also removed setcpu. :)

I have installed the no oc stock battery version, and i am getting alot of bsod when i'm charging overnight with this version - now I've removed setcpu, how would you recommend to set min cpu frequency when charging? Or should I just set my phone to stay awake when charging?

Thanks for your hard work! Apart from my charging problems, this kernal works great, thanks! :D
